COMBINED ROLLER AND PULVERIZER.

SPECIFICATION forming part Of Letters Patent N0. 627,474, dated June 27, 1899.

Application filed nv s ber 1, 1898. Serial No. 697,952. No model.

To all whom it may concern:

Be it. known that I, ALBERT lmoun, a cit-izen of the United States, residing at llousc Springs, in the county of J ell'erson and State of Missouri, have invented a new and useful Combined Roller and Pulverizer, of which the following is a specification.

This invention isacombined roller and pulverizer, the object being to provide a thoroughly eflicient device for breaking up clods of earth.

Another object of the invention is to provide means whereby the working portions of the machine will automatically clean themselves, thereby preventing clogging.

With these various objects in view my invention consists in the peculiar construction of the various parts and in their novel combination or arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a top plan view of a combined clod crusher and pulverizer constructed in accordance with my invention. Fig. 2 is a vertical sectional view on the line 2 2 of Fig. 1. Fig. 3 is a detail view showing a means for clearing the roller of clods, also dirt-guard and means for locking the elevating-shaft. Fig. 4 is a side elevation, the parts being broken away. Fig. 5 is a section on the line 5 5 of Figs. 1 and 4. Fig. 6 is ascetional viewof the drum on the line 6 6 of Fig. 5. Fig. 7 is a detail view of the shaft-elevating mechanism.

In carrying out my invention I employ a main frame composed of the side beams A, the end beam B, and the front beams C, said beams being braced by the truss-rods D. The main frame is supported upon the groundwheels E, mounted upon stub-axles E, projecting from the side beams and supported by means of the bracket-frames E, fastened to the sides of the side beams. A roller or drum F is arranged within the main frame and is mounted to turn upon the shaft G, carrying pinions G at their ends, adapted to engage rack-bars II, fastened upon the inner sides of the side beams A, said rack-bars having parallel guide-bars integral therewith, the said guide and rack bars being united at the top and providing a casting substantially in the shape of an inverted U, as most clearly shown in Figs. 2 and 4. The purpose of the rack-bars and pinions is to provide for the vertical adjustmentof the drum, whereby the ribs and blades carried thereon can be made to cut deep or shallow into the earth, and in order to accomplish this adjustment a wormwhecl is mounted upon the shaft G, nearone end, and is operated by means of a worm I, carried upon a shaft K, which shaft extends through a bearing mounted upon the rear beam and is provided with a crank K, so that by turning said crank in either direction desired the worm, and consequently the wormgear, will be revolved, which in turn revolves the shaft- G, operating the pinions G, which engage the rack-bars H, and. thereby move the drum either up ordown, as desired. The shaft K is locked by means of a suitable catch K adapted to engageasquare portion of the shaft, thereby securely locking the drum in this adjusted position. The drum D has a series of circumferential ribs D',which have sharp edges and are adapted to cut the clods of earth, and in order to further break said clods a series of cross-ribs D are arranged between the circumferential ribs D, said ribs also being sharpened at their outer edges. By means of a drum constructed in this manner the clods of earth can bequickly and easily broken up by simply drawing the combined roller and pulvcrizer over the earth.

In order to prevent the roller,with its cutting edges, becoming clogged and carrying the earth therewith, I provide a' series of spring-actuated cleaners arranged between the circumferential and cross ribs and adapted to throw on? anycarth that might accumu late between the said ribs, and this cleaner comprises a plate L, which is of a length to fit snugly between the circumferential ribs, said plates being mounted upon the end of a rod L, which passes through the drum and through a plate L carried by rods L, arranged upon the inner side of the drum, said rod L being surrounded by a coiled spring arranged between the plate I and the cross pin L, carried by the rod L, the purpose of said spring being to normally project the plate radially outward.a distance as far as the pin L will permit. While the drum is being rolled forward the plates L will be pressed inwardly wherever they come in contact with the ground; but as they rise at the rear the springs will force said plates out wardly, thereby disengaging any clods of earth that may be contained between the ribs. A dirt-guard M is mounted upon the rear beam and the seat N is also supported from the said bea-m,and between the forward beams are arranged boxes or receptacles O, in which tools or implements maybe carried. A suitable draft tongue or pole is also connected to the forward beams, which of course is provided with the usual construction of doubletree. In order to further clear the circumferential ribs, Iemploya series of scraperblades P, mounted upon a rock-bar P, operated by me us of a lever Q, connected by means of ink Q with an arm Q, mounted upon the end of the rock-bar P, the said lever being mounted upon the topof one of the side beams within easy reach of the driver, and by throwing the said lever forwardly or backwardly the scraper-blades can be thro wn into or out of position to scrape. The center one of these blades is made adjustable in order to allow for the cross-ribs and clearingplates.

The operation of the device having been fully described in connection with the description of the construction of the various parts, a further detail description of the operation is not deemed necessary.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a clod crusher and pulverizer, the combination with the main frame supported upon ground-wheels, of the vertically-adj ustable drum having circumferential cross-ribs, and the spring-actuated clearing-plates, all arranged and adapted to operate substantially as shown and described.

2. In a combined roller and pulverizer, the combination with the main frame, of the drum adjustably mounted therein, said drum having circumferential and cross ribs, the spring-plates arranged between the circumferential ribs, said plates being normally pressed outwardly by means of spring-actuated rods extending into the drum, substantially as shown and described.

3. In a combined roller and pulverizer, a drum having the circumferential and cross ribs, arranged upon its periphery, the clearingplates mounted upon rods, said rods extending into the drum-plate, through which said rod works, and the coiled spring surrounding.

the rod and bearingupon said plates, substantially as shown and described.
